An education system using satellite communications, including a satellite communication correspondence school for providing an education service, which is connected to subscriber terminals operated by subscribers for receiving lectures via a satellite communication earth station and a communication satellite, and also via a communication network on the ground including the Internet so as to distribute lectures and associated educational materials to subscriber terminals for receiving signals from the communication satellite and to communicate questions and answers of subscribers in a broadcasting manner. The satellite communication correspondence school is also connected to lecturer terminals via the satellite communication earth station and the communication satellite and via communication network on the ground. A real time lecture is simultaneously carried out by the lecturers and subscribers using a broadcasting function of the communication satellite, a return communication function using either the ground communication network or the communication satellite, and a communication function for lectures. As a result, an interactive education system can be obtained without limiting the number of educational programs, and communication expense can be reduced. |
